Given: ∠A and ∠B are supplementary angles. m∠A=4x−16; m∠B=2x+4

Prove: m∠B=68°

Drag and drop reasons into the boxes to correctly complete the proof.

  see below

Step-by-step explanation:

m∠A=4x−16

m∠B=2x+4

Supplementary means 180°

  m∠A + m∠B = 180°

  4x−16 + 2x+4 = 180

             6x - 12 = 180

                    6x = 192

                      x = 32

m∠A = 4(32)−16 = 112°

m∠B = 2(32)+4 = 68°

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
